How moisturizing is it?

Highly moisturizing: Peter Thomas Roth Potent-C Vitamin C Bright & Plump Moisturizer has a moisturizing rating of 6.2 out of 10.

Is it more humectant or occlusive? Significantly more humectant. It has a low occlusivity of 2.3 out of 10 and a maximum humectancy of 10 out of 10, primarily due to the high content of Propanediol (est. ≈10.1%) and Glycerin (est. ≈3.1%).

Please refer to the Ratings section below for details of the moisturizing rating calculation.

Anti-wrinkle efficacy

According to CreamScan analysis, Peter Thomas Roth Potent-C Vitamin C Bright & Plump Moisturizer has a zero anti-wrinkle rating.

It contains Tetrahexyldecyl Ascorbate and Gluconolactone, two ingredients marketed as effective in reducing wrinkles. However, the studies supporting the anti-wrinkle claims of these ingredients provide insufficient evidence of efficacy according to CreamScan Research Evaluation Standards. Therefore, these ingredients do not generate the anti-wrinkle rating.

Please refer to the Ratings section below for details of the anti-wrinkle rating calculation.

Antioxidant benefits

We estimate that Peter Thomas Roth Potent-C Vitamin C Bright & Plump Moisturizer is rich (> 3%) in antioxidants, specifically Tetrahexyldecyl Ascorbate (est. ≈10.0%), Tocopheryl Acetate (est. ≈3.0%) and Ferulic Acid (est. ≈2.0%).

A key benefit of antioxidants is their ability to reduce oxidative stress caused by free radicals and therefore prevent accelerated skin aging. Studies also show that antioxidants can protect against environmental damage such as UV radiation and pollution, and help reduce inflammation and skin redness.
